Just recently discovered these.Without even thinking my brain is saying get them, just pure lust.I was thinking I would eventually replace the ugly S Works chainrings with Praxis but those don't look so great either.If the shifting is as good as the S Works rings with my Ultegra Di2 I would be more than happy.I weight 138 lbs so I don't know if flex would be an issue. Crank is S Works compact 34/50Not much info on these so please help if you have them.

I've used both but neither on DI2. Personally, with mechanical systems I would only use Dura-Ace, Campy, or Praxis rings. Nothing else has ever come close to those three in terms of performance. KCNC just couldn't shift as smoothly. Maybe with electronic stuff it doesn't matter, though.

There's a new version of the KCNC Cobweb chainrings designed to be stiffer....I also would recommend Specialites TA. Personally I'm using Tune chainrings and the performance is very good with Campy EPS.

I have a set of 130bcd on rotor cranks on my r5 and they are very flexy. I love the look, price, and weight (they go very nicely with M5 brakes!), but I would never purchase them again. Shifting is very poor and I get noticeable flex in the big ring when getting on it. I am a 175 lb cat 1 though, so I don't know if you would have similar issues....
